| Experimental Observation of the Blob-Generation Mechanism from InterchangeWaves in a Plasma (2008) | |||||||||||
Abstract | |||||||||||
| The mechanism for blob generation in a toroidal magnetized plasma is investigated using time-resolved measurements of two-dimensional structures of electron density, temperature, and plasma potential. The blobs are observed to form from a radially elongated structure that is sheared off by the $E \times B$ flow. The structure is generated by an interchange wave that increases in amplitude and extends radially in response to a decrease of the radial pressure scale length. The dependence of the blob amplitude upon the pressure radial scale length is discussed. | |||||||||||
